Hi,
I came to USA 15th Oct 2011 with H1B visa. My wife came here 20th Nov 2011 with H4 visa. Since ITIN is required while filing the tax returns, if I submit W-7 now, I will receive her ITIN by end of April. But we need to file before 15th April. So can I file without her ITIN? Please let me know how to proceed.
